Charge your cellphone in 30 seconds

Still very far off of charging cellphone batteries... At the moment, all it can power are low-powered LED's... But the idea is a good one.
 
Send this to Angie and ask her how what the chances are of any of her pupils doming up with something similar. And I am not talking about Model C schools - they perform despite the DOE's best efforts.
 
This will stuff up your battery big time. I've heard Samsung have had similar technology but don't use it as your battery lifespan deteriorates drastically.

Agreed. I'm not questioning her genius, but using a cap to charge your phone generally sounds like a bad idea. With the amount of current this will push through your phone, for one, it would generate a lot of heat.

Additionally, super capacitors are not a new invention and they usually suffer the same ironic flaw; insufficient energy capacity. They just don't have the juice to fully charge a phone. Though this might be out of context, little is said about the cap's physical specs.
 
This is not new technology. See http://en.wikipedia.org/wiki/Electric_double-layer_capacitor. From the article: "EDLCs can drive low-power equipment such as PC Cards, photographic flash, flashlights, portable media players and automated meter reading equipment.[68] They are advantageous when extremely fast charging is required. In professional medical applications, EDLCs have been used to power a handheld, laser-based breast cancer detector (55 F to provide 5.3 W at multiple voltages) that charges in 150 seconds and runs for 60 seconds)". So I do not know what she did different to deserve the price.

That helps! Seems her capacitor certainly has a much higher energy density per kg than current super capacitors, but still much much lower than, say, the capacity of a Li-Ion rechargeable. I still don't see any way it would charge your phone in 20 seconds, unless you replace your phone battery with the cap (or have some kind of hybrid). Which is just as silly.

But in it's own field of applications, it is certainly exceedingly impressive.

More interesting, I found, is the fact that she did not get 1st place, yet she's been advertised the internet over. And she tied with a 17 year old "who figured out new ways to measure dark matter and energy in space." :wtf:
 
Don't you know about the Microwave app???

You load the app and you put your phone in your microwave for one minute and is FULLY charged.

All systems. iOS, Android, Blackberry, windows phone & symbian.

:D
